Abstract
A control system of automotive air conditioning device comprises a heater/cooler unit having therein a plurality of control doors by which various air flow modes are provided. A plurality of identical actuators are employed for actuating the control doors. Each actuator includes an electric motor for driving the corresponding control door, a position detector for issuing a current position signal representative of the current angular position assumed by the corresponding control door, and a control circuit for controlling the electric motor by processing both the current position signal as well as a target position signal applied thereto. A control unit is further employed for totally controlling the actuators by means of a multiplex communication carried out between the control unit and each of the actuators. The control unit issues the target position signal to each of the actuators.
